Features of the Multicast mode:
- To get a multicast video in Axxon PSIM (see Configuring multimedia receipt using RTSP protocol) set the multicast value to the RTSP parameter in the HKEY_LOCAL_MACHINE \SOFTWARE\AxxonSoft\PSIM\Video\TransportProtocols registry section (for 64-bit system the path is HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\AxxonSoft\PSIM\Video\TransportProtocols) on computer where the Camera object is created. For detailed information on this parameter, see Changing the transport protocol used by IP-device.
- RTSP Server can broadcast simultaneously in Multicast and Unicast modes. Receiving both such streams on the Axxon PSIM client is impossible due to RTSP key which determines the connection mode (see above). However, the VLC player allows receiving streams in both modes in the same time.
- The ports that are assigned to each camera in this mode will not be displayed in the Windows OS Resource Monitor and other similar operating system resource monitors.
Using the Multicast mode allows you to reduce the load on the Server by reducing the amount of transmitted data. To distribute the transmitted signal among different RTSP ports, do the following:
...
To connect to Server and display video in the video player that supports RTSP protocol, specify the address of data source in the format given in the table:
Address | Example | Description |
rtsp://ServerIP address[:Port]/CameraNo[?stream_id=StreamNo] | rtsp://127.0.0.1/1 | Viewing default stream from Camera 1 if default port is in use |
| rtsp://127.0.0.1:555/1 | Viewing default stream from Camera 1 when broadcasting in Multicast mode if default port 555 is in use. Note. Connection to the RTSP stream is performed via the broadcasting adapter IP address, not by the destination IP which is specified in the settings panel of the RTSP Server and is used internally | |

If the archive is in a different time zone, you need to specify the time taking into account the time difference. For example, if the archive is located in UTC+4 and you need a period from 15:02:00 to 15:49:00, the above example is suitable. On the settings panel of the RTSP Server object, you must select the specified Backup archive for the corresponding camera. The VLC player compatibility mode must be enabled to view in VLC Media Player |
